I have no idea how the Python dev's use IOCP with sockets.

They can’t figure out a way to support file I/O notifiers (of the kind
commonly used with event loops) with it. If you know of a way to do it,
please tell us.

Well, usually, iirc, been a while, when GQCSEX returns we take the
WSAOVERLAPPED and convert it to our extended structure. Basically
similar to how Linux uses offsetof to extend node structures, or on
Windows CONTAINING_RECORD, then we can use that to pass into a function
called on_read, on_write, on_accept, on_connect, ect... type of
functions.

 Does that require explicitly queuing a read or a write operation?
 According to the platform support notes
<https://docs.python.org/3/library/asyncio-platforms.html>,
ProactorEventLoop does not allow the addition of reader/writer callbacks
for caller-supplied file descriptors.
 Remember what these callbacks do: they notify that the FD will accept a
read or a write, not that a pending read or write has completed.

Well, I still don't know how Python is implementing things. To busy with some other work to even take a look right now. Field related, fwiw here is one of my experiments:

Keep in mind that successful IOCP means the completion of an io action has occurred, or an error has been raised. It could be a new connection, a buffer was sent, data has been read. That is the C (completion) in IOCP, see?
